You're dreaming. There is little to no interchangeability among different makes of plumbing fixtures. If you can open the wall on the non-tile side, it "might" be
possible to install different valves/faucets without disturbing the tile.

SOMETIMES, an upscale brand, such as Newport, uses the parts from a mainline company, such as Central or Pfister, as its base. In those cases, you can use parts from the original manufacturer to redo it. But, you have to do due diligence and determine whether the base is proprietary or not.

Many (most?) companies make their internal parts such that they specifically aren't interchangeable with other companies stuff thus forcing you to buy directly from them. The only thing (usually) guaranteed to be universal is the end connection to the supply so you can hook it up and that may even be a proprietary adapter.
